Using svls with QTCreator

[janrinze]

After building svls I tried to use it as a language server for QTCreator with moderate success. Most of my sources are Verilog instead of System Verilog and thus there is a lot of messages regarding that. The language server thus works with QTCreator and that's a good start. There obviously is no real support for verilog in QTCreator but I really like the editor. Also having embedded soft cores with both verilog and C/C++ makes it a real game changer. If anyone has any experience to make this language server more useful in QTCreator then please add that to this issue.
